IMPROVEMENT IN SPOKE-IVIACHINES.

Specification forming part of Leiters Patent No. 52,`30, dated January 2.1, 1866.

To all whom lit may concern:

Beit known that I, RALPH H. BOYNTON, of Oshkosh, county of 'Winnebagm State of Wisconsin, have invented new and useful Improvements in Machines for DressingI Spokes and I do hereby declare that the following is a full, clear, and exact description ot' the construction and operation ot' the same, reference being had to the annexed drawings, makinga part of this specification, in which- Figure 2 is a plan, looking' down upon the top; Fig. 3, a side view ofthe side A, Fig. 2; Fig. 4, a side view ofthe side B, Fig. 2; Fig. 5, an enlarged vertical longitudinal section, showing the dii'erent positions ofthe levers m m as operated upon by the revolution ot' the cam or rotating pattern s Fig. G, a lateral vertical section through the line x x, Fig. 2; and Fig. 7, a vertical section through the line z e, Fig. 2.

The same letters refer to like parts on the different sections of the drawings.

A A, a a, and B B on the different sections represent rails and posts ot' a rectangular frame, constructed in any suitable manner to support the several parts of said machines.

The operation is as follows: Power being applied, a band, w, from the pulley O, Fig. 4, toa small pulley upon the arbor which carries the cutter-heads gives motion to the cutter-heads in the direction of the arrow z', and a band, x, from the opposite end of the same arbor to the pulley D, gives D revolution, as indicated bythe arrow z.a pinion, g, hung upon theopposite end ofthe samejournal with D, meshes into the wheel E, (or drives it by frictiom) givingE motion in the direction shown by 2', and hung upon thejournal with E is a small pinion, e', meshing into the gear-wheelf, givingf motion, as shown by 2". Hung upon the shaft withfis the rotating pattern s, which operates the levers m m, Fig. 5, they in turn acting upon the bent arms tt, Fig. 6,

which in their turn actuate the cutter-heads u u, forcing them closer together, and allowing them to assume their original position again with each revolution ot' the pattern s and gear-wheelf. The endless chain or belt y is carried forward on drums at either end of theframe. One ofthe drums, being hung on the shaft with the wheel f, receives motion in the direction with j'. The pulley D and pinion g are hung upon a vibrating journal, Fig. 7, one end of said journal being hung upon the upright bar of', which is jointed to the vibrating lever o at 0, the upper end being secured by a bolt through a slot in said bar o. allowing it free motion.

It will be seen that when the lever o is depressed, as shown bythe dotted lilies, the pinion g will be thrown into gear with the wheel E, which drives j', thus giving feed-motion to the endless chain or belt y.

rlhe hanging frame 7c is jointed to uprights at 5 5, Figs.3 and 4. The ottlce ofsaid frame is to carry the journal m of the cutter-heads un, and is so operated that it rises and falls with each revolution ofthe wheeljl The cutter-heads u u are secured to collars which slide freely upon the arbor m. Through this arbor, and lengthwise with it, is a slot, through which are passed keys, which keys are fast in the cutter-heads, but slide freely in this slot, allowing the cutter-heads a free lateral motion. This motion is given the cutter-heads by the journals 3 3, Fig. 6. The arbor m is hollow to admitthrough it thejournals 3/ 3, the inner ends being' attached to the cutter-heads, the outer ends having their bearings on the upright ends of the arms t t. When the horizontal ends of the arms t t are depressed to the dotted lines seen at Fig. (i the cutter-heads will he forced close together. The arms t t are jointed at 3 3 and hinged at 4 4, so that the horizontal ends at 3 3 have a perpendicular motion and the upright ends have a lateral motion.

The levers m m, Fig. 5, are hinged at 011e end, m at 5, and m at 4, the opposite end oi m being jointed at 3. The two levers are connected by a cross-bar, a, which is movable, and the lever m is connected with arm t by a stud, 3. During the revolution ofthe rotating pattern s the end of the lever m is depressed to the dotted lines, Fig. 5, and the levers being connected by the bar n, m will be drawn down, as at 3, thus forcing the arms t t into the position shown by dotted lines, Fig. 6.

6, Fig. 4, is a spring fastened at 8 and connected with the arm t bya cord running over a pulley at s s. When the pattern s has made a complete revolution the lever m will be free, and the action of the spring 6 Willlift the horizontal ends ot' the arms t t, as at 3 3, Fig. 6, thus throwing apart the cutter-heads and restoring the levers m m to their original position.

H, Fig. 4, is a bent lever actuated b v a stud upon the wheelf, whose office it is to raise and lower the hanging frame 7c. This is done as follows: In k, at b, 4, is set a socket, i', and on the short arm ofthe lever 7L is jointed a stud, i2, one end of this stud fitting into the socket fi', the other end jointed to 7i by a bolt and nut, the bolt working in a slot in h, so as to be adjustable at will. The vibration ofthe frame la is to adapt the perpendicular action of the cutter-heads to spokes differing in thickness.

It will be observed that by placing the connecting-bar a in the different positions seen at Fig. 5 the action upon the cutter-heads will be varied, thus enabling said machine t-o dress spokes differing in taper.

Having described the several parts of said machine separately, I will now describe their united action.

Power being applied, the pulley G is set in motion inthe direction indicated by the arrow z. Motion is thus given to D and g. The long arni of the lever o being depressed, g is thrown into gear with E, setting all the parts in motion. The inaterial is then placed upon the moving bed 0r chain y, (being held down while passing under the cutters by rolls 0,) so that so much of the spoke as will be required for the tenon will have passed under the cutter when the stud on the wheel f comes in contact with the lever 7i. The wheelf, in its further revolution, lifts the lever h, which allows the frame k to fall slightly, making a depression in the spoke, then lifts it to the dotted line o, in which position it remains until the spoke has passed from under the cutters.

During the revolution ot' the pattern s the cutter-heads, through the medium ofthe levers on and m and arms t t, are gradually forced nearer together until the complete revolution of the pattern, when the spring 6 brings thein back again to the starting-point, and a repeating operation completes the job.

Having thus described my invention, I will proceed to state what I claim as new and desire to secure by Letters Patent:

The rotating cutters u u, bent levers et 4, lever m', and cam-shaped pattern s, arranged with reference to each other and to the endless bed or chain y substantially `as and for the purpose herein set forth.

It. H. BOYNTON.
